this is all MLB-realted stats, not mil nonsense. the movement part, for example, will require some years in MLB, but you can guesstimate it fairly accurately too, but you wil be surprised occasionally, both negatively and postively for the same value, regardless.

stuff is probably the stongest correlation...

extremely high control can sometimes overcome a lower stuff, though. more rare, than the opposite though.

extreme movement will not make up for low stuff/control.. but it is important, nonetheless to not be abysmal.. resulting HR/9 is the key here... as long as not too high they can reach "elite" levels of performance.

basically ahigh stuff with just ~average control and ~61/100 movement will net a very likely great pitcher. Max/max+ stuff. if rp, max+, sometimes ~max-ish.

not limited to that, of course... you will find exceptions, but nothing you can bank on as consistently as what i mentioned (modern-like stats league only reference)... it's like going to vegas and betting against the odds, but when it happens, just take it. those exceptions require years of results to recognize, and by that time they may be too old to bother with.

one more think on movement -- if he's ~60/100 and "extreme groundball pitcher" it can only go down and it can go down A LOT! lol... so know what factors add up to movement. i think even pitch type influences movement (turn 100% accuracy on and compare profile ratings as you change them -- editor values are not the same as what's displayed, but with 100% accuracy it is how it's used by engine, same with 'stuff' - includes velo and i think gb%? note in editor about it.)

defense helps, but it's not the reason a player swings from a 3.50 to a 5.00 ERA or any 'bigly' effect like that (haha).

what's in their repertoire will influence results too... E.G. a really good KB included will result in lower BABIP against than other combinations of pitches.

i think a changeup elevates hr/9 a bit, but also increases other really good things.. so an elite changeup is an aweome pitch, but a mediocre one is maybe worse than a mediocre 'other' pitch.

the game uses overall stuff in the math, but clearly types of pitches do matter due to these obvious trends you can witness... the KB-effect is plain as day to see. the changeup is more of a guess form my experience and how it works in RL too. bad changeups get hammered worse than a bad fastball (which would be more about placement, i guess for a fastball) different combinations have some influence over results, even if overall stuff is all that is used. there must be some other impact not as apparent.
